Sleep is very important. A person who does not sleep dies faster than a person who does not eat. We spend about a third (1/3) of our lives in sleep. That"s about 121 days a year!     How much sleep do we need? We are all different. A baby needs 16 hours of sleep every day. Children 6 to 12 years old need an average (平均) of 10 to 12 hours of sleep. Teenagers need 9 to 10 hours of sleep. An adult needs an average of 7 to 8 hours a night. There are some people who need only 3 hours of sleep. Others need 10 hours of sleep. After the age of 50, the average sleep time goes down to 6.5 hours a night. We need less sleep as we get older.      About one in three Americans has a problem with sleep. Many of these people cannot fall asleep. The name of this problem is insomnia. Some people say, "I didn"t sleep all night." But that"s not really true. They may sleep lightly and wake up several times. In the morning, they only remember the times they were awake (醒着), so they think they were awake all night.     This is not a new problem. Many famous people in history had insomnia. Some of these people had special ideas to make them sleep. Benjamin Franklin had four beds. He moved from one to the other to fall asleep. Mark Twain had a different way. He lay on his side across the end of the bed!

If the only sports you do are dancing your fingers across your keyboard, you could be in serious danger of more than just becoming fat!        Do you feel sleepy, like something is weighing down on your head? Do you feel forgetful? Do you sometimes feel uncomfortable up and down your neck and lower back, and you can"t explain why? Do you get sick often? It could be radiation (辐射) from your computer causing it. If you spend three hours or more a day in front of a computer, (and at this point, who doesn"t?) you are more easily harmed by these hazards (危害).         We have got so used to using computers that we don"t often think of them as dangerous sources (来源) of harmful (有害的) radiation. A safe amount radiation is 25 V/m (Volts/meter). Do you want to guess how much our personal computers give off?       ★ Keyboard: 1000 V/m        ★ Mouse: 450V/m       ★ Monitor: 218 V/m       ★ CPU: 170V/m                  ★ Notebook computers: 2, 500 V/m       Ways to Protect Yourself from Harmful Computer Radiation:       1. Decorate your desk with cactus (仙人掌) plants, they take in radiation.       2. Drink two to three cups of green tea a day and eat an orange daily. The vitamins in tea leaves and            oranges protect us from radiation and keep our eyes healthy as well.       3. Use a screen filter (过滤器) for your monitor.       4. Avoid having metal objects nearby on your desk.       5. Put the back of the computer to the wall. Most of the radiation comes off the back.       6. Keep your monitor at least 50cm away from your face.       7. Keep your computer rooms ventilated (空气流通的).       8. Eat healthily-especially fruits and vegetables.       9. Don"t fall asleep on your computer. Turn it off if you have to rest nearby. The ways above are useful,           why not have a try at once? A. 根据短文内容简要回答问题。 1. Which is safer, using a desk computer or a notebook computer?    _______________________________________________________________________ 2. Which of the nine ways mentions diets?    _______________________________________________________________________ B. 将短文中划线的句子译成汉语。 3. _______________________________________________________________________ 4. _______________________________________________________________________
C. 请给短文选一个适当的英文标题。  5. Which is the best title of this passage?  ________
[     ]
A. Harmful radiation B. Computer problems C. Protect yourself from computers D. Computer radiation: a silent killer
